Urgh the not knowing is the worst for an anxious mind like mine!
I can see my first pic looks like your tick @DontMakeMeShushYou
But I reexamined the scene and there really weren't any legs at any point and as I was trying to tweezer it it sort of changed shape just like a blister. It wasn't this smooth and round. And all I was left with were two little fragments (skin?), the rest was just blood.
I guess I will just never know...
